Application September 10, 1951, Serial No. 245,801

2 Claims.

This invention relates to improvements in mountings for telescopes as applied to rifles and the like, and it has reference more particularly to mountings adapted to be fixedly secured to the gun and comprising supports therein by which the telescope can be secured, and which supports are adjustable to permit the proper or desired alignment of the telescope with the bore of the rifle barrel.

It is one of the principal objects of this invention to provide mountings that may be applied to a gun for the functional holding of a sighting telescope, and which mountings will not in any way interfere with sighting by use of the sights with which the gun is originally equipped if such becomes desirable.

It is also one of the principal objects of this invention to provide a pair of mountings that may be applied to the gun or rifle for the reception and holding of the opposite end portions of the telescope, and which mountings are each equipped with segmental holding bands that are applicable about the end portions of the telescope and may be adjusted as may be required to properly align the telescope with the gun barrel.

Still another object of the invention is to provide telescope mountings of the above stated character that are sturdy, long lasting, easily adjusted and relatively inexpensive. Furthermore, a telescope mounting that can be easily and readily applied to guns of different kinds and calibers and which may be easily and quickly detached if such should be desired.

Still further objects of the invention reside in the various details of construction of the parts of the device, and in their relationship and mode of use as will hereinafter be fully described.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein Fig. 1 is a side view of a portion of a rifle, showing a telescope mounted thereon by the paired mountings embodied by the present invention.

Fig. 2 is a plan, or top view of a portion of the gun showing the plates secured to the gun frame for attachment of the telescope mountings.

Fig. 3 is a breech end view of the gun barrel as equipped with the present telescope mountings.

Fig. 4 is a cross-section of the mounting, taken on line 4-4 in Fig. 3.

Fig. 5 is a perspective view of one of the mountings, with parts thereof shown in dis-assembled relationship for better understanding of details.

Fig. 6 is a perspective view of an alternative form of peep sight plate for use with the mountmgs.

Fig. '7 is an enlarged sectional detail of a part of a mounting.

Referring more in detail to the drawings In Figs. 1 and 2, I have shown that portion of a gun to which the present telescope mountings are applied. This part of the gun comprises a frame portion ID in which the breech end of the gun barrel II is secured; the frame, in turn being secured in the gun stock l2. The frame l0 includes integral, upstanding blocks l3 and [4, at its opposite ends and in spaced relationship along the barrel, and it is upon these blocks that the telescope mountings of the present inv Fig. 5 will be described in detail, with the understanding however that this description relate equally to both mountings A and A.

First it will be explained that the mountings A and A are secured to their respective base blocks l3 or l l'by means of attaching plates 20. Each plate, as seen in Fig. 5, is rectangular in plan, with a flat, horizontal top surface 20a, parallel opposite edges 20b, and a bottom surface 200 that is arched or otherwise shaped to fit flatly against the top surface of the base block [3 or l4 to which it is to be attached. The attachment of each plate 20 to its base block is by means of two screws 2l2l, seen in Fig. 2, passed downwardly through holes 22 therein and threaded onto the base block. The relationship of the two plates 20-20 is seen in Fig. 2 wherein they are shown as being secured for the reception of the mountings A and A. Also, the top surfaces of both blocks are in the same horizontal plane, and this plane is parallel to the bore of the barrel.

It is to be observed by reference to Fig. 3 and Fig. 5 that the lower portions of the longitudinal side edges of the plates 20-20 are beveled inwardly and downwardly, as at 20$, for a purpose that presently will be explained.

The mounting member A is formed from a single piece or block of a suitable material, for example a block of aluminum. It is disposed in an upright position upon the base block l3 and is rigidly secured thereto. To provide for its securement, the member is formed with an upwardly arched bottom surface which permits it to be fitted to the correspondingly arched top surface of the block l3 at opposite sides of plate 20. Also, it is formed with a key-way slot 24 across and opening to the bottom surface, that is designed to snugly receive the plate 20 therein in a dove-tailed connection; the manner of assembly of part A with the plate being to place the lower end of the mounting upon the block I 3 at one end of the key plate 20, then to slide it over the plate to the position or relationship of parts shown in Figs. 3 and 4. Then, for its fixed securement, screws 25, as shown best in Figs. 1 and 3, are threaded through holes 26 in the lower side walls of the mounting and are seated at their inner ends in sockets 21 formed in the side surfaces of the plate 20 to receive them.

The mounting A is formed across its upper portion, in the direction of the barrel H, with a deep out recess 30 designed to contain one end portion of the telescope and its holding means. The recess 30 has a semi-circular bottom surface and vertical opposite side surfaces. Located within the lower portion of the recess 30 is a short, cylindrical telescope encircling band 3|, made up of two separate, semi-circular segments as best seen in Fig. 3; these being adapted to be fitted about the telescope barrel as contained in the mounting. After the band segments have been applied about the telescope barrel and seated in the recess 30, the open upper end of the recess is closed by a cross-bar 32 fitted therein and secured at its ends by screws 33 that are passed through holes 34 in the upper ends of the side wall members and then threaded onto holes 35 in the ends of the bar.

It is noted more particularly by reference to Fig. 4, that the band segments are centered in the recess between upper and lower sets of cross pins 36--36 that extend through the recess, between its opposite side walls. The disposition of the two band segments in the recess is as seen best in Fig. 3, wherein it is noted that the lower segment is supported at bottom and one side of the recess, upon pivot pins 40-40' that are set in holes 4| provided therefor in the mounting. The pivot pins are pointed and the points are received in V-shaped channels 42 cut in the outer surfaces of the segments and in their circumferential direction as shown in Fig. 7. Also, these two pivot pins have encircling flanges 43 formed near their pointed ends that rest against rubber cushioning gaskets 44 set in the holes 4| as shown in Fig. 7. This manner of mounting the pivot pins 4040' is to permit aligning adjustment of the telescope as presently more fully described.

The upper semi-circular band segment is similarly engaged by adjustable pivot screws 4646', which are located diametrically opposite the pivots 40-40, one being threaded through a side wall of the mounting into the recess and. the other being threaded downwardly through the cross-bar 32. Each pivot screw 46-46 is pointed at its lower end and the end seats in a V-shaped channel 42 in the band segment.

The telescope T is assembled with the mountings as follows: With the cross-bar 32 and the upper set of cross-pins 36-36 removed from each mounting, the lower segments of the holding bands 3| are applied to opposite end portions of the telescope barrel, and the barrel laid into the recesses 30 of the mountings. The band segments are disposed between the lower cross pins 36-36 and upon the points of the pivot pins 40-40 as shown in Fig. 3. Then the upper seg- 4 ments of the holding bands are laid into position, and the cross bars 32 placed and secured in the mountings across the upper ends of the recesses. The upper set of cross-pins 3636 is then applied to the mounting to hold the upper segment between them. Then the adjusting screws 4B46' are applied to the bars 32 and sides of the mountings with their inner, pointed ends seated in the V-shaped channels of the band segments. 1

Vertical and lateral adjustment of the telescope ends, as held in mountings A and A may then be accomplished by manipulation of the screws 4646'; it being understood that the rubber cushions 44 associated with the pins, 4040 permit yielding movement of the telescope in the mountings under control of the adjusting screws. These screws may be held against free turning by use of spring clip devices as indicated at 41 in Fig. 5.

In order that the mountings A and A, as applied to the gun, will not interfere with sighting in the usual way, each mounting has an opening 50 therethrough located below the recess 30. These openings of the two mountings, as shown in Figs. 3 and 4 provide for full view of the gun sights by looking directly through them.

As a peep sight attachment, I have provided a thin metal plate 60, for securement over the opening 50 of either mounting but preferably the rear mounting. This plate has a center piece 6| which may be made luminous with peep sight openingl-rr-thereirTlre'pTa'tg s secured by screws 63 at its top corners.

As an alternative, the plate might have a hinge plate mounting as shown at 65 in Fig. 6, thus to provide that it can be flipped up or down out of the line of sight if such is desired.

When the peep sight plate is used the rear sight of the gun, as seen in Fig. 1, would be lowered out of line of sight or is removed.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent, is:

1. A telescope mounting block of the character described adapted for fixed securement on a rifle barrel and having a, recess deeply formed therein and opening to the top thereof for the reception of a telescope barrel, and a closure member removably fixed in the block across the open end of the recess ahtelescope milllntingcollar disposed in the closed recess with clearance about it for yertical and lateraLadjustment, upper.andlower sets of paired rods mounted in the block and extended through the recess to receive the upper and lower portions of the collar between them as a means for holding the collar and telescope as secured therein against longitudinal movement in the block, and means in the block for adjusting the collar vertically aiidlaterallyrin the block. 2. A telescope mounting as recited in claim 1 wherein the said collar comprises two semi-circular cylindrically curved segments, and the means in the block for adjusting the collar comprises two yieldable supports, mounted in the block at the base and at one side of the recess respectively, to engage with opposite end portions of one of the segments, and two adjusting screws threaded through a side of the block and the closure member, respectively, diametrically opposite the two yieldable supports and engaged with opposite end portions of the other of the said segments.
